[3.05] A search for further irregular satellites of Uranus and Neptune.

We have conducted a wide-field search for new satellites of
Uranus and Neptune covering most of the Hill spheres of both
planets. Our search was motivated by the discovery of the
first 2 irregular satellites of Uranus in 1997 (Gladman et
al 1997, Nature, v 392, 897) during a cursory CCD search of
the surroundings of the planet; clearly a more complete
survey of the environs of both planets with modern
instrumentation on a 4-meter class telescope was warrented.
In our recent survey we examined the regions around both
Uranus and Neptune using data obtained in July 1999 using
the wide-field CFH12K mosaic on the 3.5-meter Canada France
Hawaii Telescope. The coverage within this area is almost
complete: at least 95 percent of the region within 1 degree
and exterior to a box 6 arcmin in diameter centered on each
planet has been covered to magnitude roughly R=23.5. We have
at least one new candidate satellite of Uranus and have
discovered many new trans-neptunian objects as a by-product
of our search. Recovery observations are scheduled for
August 1999 from the Palomar 5-meter and Apache Point
3.5-meter telescopes. The current status of this program
will be reported.
